Introduction to FCAO-1 Cement Free Calcium Oxide Automatic Tester:
1. Overview:
Free calcium oxide (fCaO) is an important indicator for measuring the quality of clinker, and accurate and appropriate determination of fCaO in clinker is particularly important for cement quality control The FCAO-1 automatic measuring instrument for free calcium oxide in cement uses conductivity analysis to determine the content of fCaO, reducing previous human titration errors and improving measurement accuracy. The process of measuring the content of FCaO can be automatically completed in just a few minutes, and the test results, alarms, etc. can be displayed and printed automatically. It greatly shortens the measurement time, reduces labor intensity, demonstrates obvious advantages of speed and convenience, and plays a positive and excellent role in production quality control2.
